Look at your data comparison again and ask: Should it be 4:1 or 1:4?

I must be ovelooking something obvious Richard. Measuring through the
4:1 balun with my transmission line on the high side of the balun and
my analyzer on the low side, I obtain the values listed under the 4:1
MFJ Balun column in my earlier post. It doesn't look backward to me.
I'm getting lower impedances just as I would expect. What are you
trying to tell me?


Moving the feed along a dipole does not change its resonances and anti-resonances
(some prefer the terms series and parallel resonances); it changes their impedances

I agree

However, the balanced dipole shows low resonance (series) and high
anti-resonance (parallel) impedances. You are showing consistent low
resonant impedances.

My sloping dipole isn't balanced. Its being fed off center. The OCF
dipole (at least by design) is near (but not on) the peak of a current
loop on 80, 40 and 20 meters (even harmonics). Don't the lowest
impedances occur at current loops? Why are you surpised my impedances
are low rather than high on even harmonics?


Well, in my review of all of your correspondence, you neglect to tell us just how far off from center the feed is, and how much slope there
is to the overall wire, and even how long the wire is.

My apologies. Antenna is 136 feet long. Feedpoint is 35% from the end
that is the highest in the air. Height of high end is about 40 feet.
Height of low end is about 10 feet. Feeding with 300 ohm twin lead
that is 95 feet long (actual length, not electrical length),


Let me know about matches in between 40M and 20M.

The antenna is resonant (zero reactance) at 3.56 Mhz, 8.05 Mhz and
15.7 Mhz. My tuner is required for working in the Amateur bands.
